This Greenhouse is our new Happy Place.

We were originally quite skeptical about the design of this greenhouse but we are now super happy with it. I think our favourite feature is the plastic. It isn't just super thick but it has rip-stop! Some of the grommets aren't as sturdy as they should be but the greenhouse made it through our very windy East Coast winter just fine. ** We built ours on a concrete foundation so it's very well anchored.

Greenhouse review

This was very simple to install. My only suggestion would be that the rope come on a reel rather than a bundle. It got very tangled and was a nightmare to try and use once that happened. Plus there wasn’t enough of it so we had to use zip ties, which was fine too. Overall this greenhouse is amazing!
